The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures, growth in earnings per share, compelling growth in net income and expanding profit margins. We feel these strengths outweigh the fact that the company has had lackluster performance in the stock itself. You can view the full Intuitive Surgical Ratings Report.
